Tracking problem in spherical coordinates with range rate (Doppler) measurements, which would have errors correlated to the range measurement errors, is investigated in this paper. The converted Doppler measurements, constructed by the product of the Doppler measurements and range measurements, are used to replace the original Doppler measurements. A(More)
Though a Monostatic-Bistatic Composite High Frequency Surface Wave Radar Network (MBC-HFSWR Network) is established to cover the shortage of the monostatic radar, how to judge the real target update from the plausible measurements to initiate tracks quickly and accurately still remains a challenging problem. A novel method utilizing unconventional(More)
High frequency surface wave radar (HFSWR) is superior to detect and track beyond-the-horizon targets but susceptible to the ionosphere interference because of the specific wavelength. Seeking out the real target points from plenty of false ones is an obsessional problem for data association. This is commendably solved by establishing a new radar system, the(More)
The monostatic high frequency surface wave radar (HFSWR) can not detect the target altitude information directly and lacks the capability of classifying whether the aircraft is flying over the horizon, which is essential for the air threat assessment. In this paper, with a transmit-receive (T/R) station and a receive-only (R) station HFSWR (T/R-R HFSWR),(More)
When jammer is near the axial of sensors, there is a problem that the location precision is very low when using traditional trigonometric location algorithm. In order to solve this problem, projection location algorithm based on geometry relation between jammer and sensors is presented. Because the location precision of near area using this method is higher(More)
